FAST Mode


One advantage using a MultiX++ full parallel system is the possibility to fire several apertures simultaneously on one or several probes improving greatly the productivity of an inspection.

  

PARALLEL SYSTEMS

SEVERAL APERTURES FIRED SIMULTANEOUSLY

 

For a 128-element system, up to 4 sub-apertures can be fired in parallel leading to gains in productivity of nearly x4 with no compromise on the resolution. The following illustration shows the example of four sub-apertures fired simultaneously using the fast mode interface.

FAST MODE INDUSTRIAL APPLICATION

HIGH SPEED COMPOSITE INSPECTION

mixed mode -

A carbon epoxy plate was inspected with a MultiX++ system using the new Multi2000 V8 version. Thanks to the parallel architecture of the MultiX++, two sub-apertures were fired in parallel with a 64-element probe. A substantial improvement (x2) of the inspection speed, up to 400mm/s, has been obtained with a pixel resolution of 0.5x0.5mm, including full A-Scan storage. Multi2000 V8 is linked directly to CIVA Analysis for powerful post-processing, analysis and 3D visualization of defects.
